HERBICIDES Turfgrass Herbicides T he turfgrass herbicides industry is everevolving. Every year brings something new. From expanded labels to new active ingredients to new uses for existing products, there are formulations and active ingredients to combat nearly every known species of weed. Some seek out weeds and kill them selectively while others kill indiscriminately. With so many options available, it is challenging to quickly find what you need to solve weed problems, but the following charts are designed to offer you a comprehensive, quick resource to herbicides. In them, you'll find a list of active ingredients and which weeds (grassy and broadleaf) they control. They include a description of other chemical characteristics, as well, such as whether the formulation is liquid or granular, selective or not, and whether the product is also labeled for ornamental use. Note that the purpose of this chart is to list chemicals registered for use on turfgrass. Some of these are also labeled for ornamentals. However, we'll profile products designed strictly for ornamentals in a chart of their own. User's manual When you turn this page, you'll find a twopage chart that describes every chemical (by common name of active ingredient) listed within the entire herbicide guide. These pages describe each chemical's characteristics, and define the following: species are tolerant of the chemical) You may notice some listings in green type. This indicates a new active ingredient for the turf and ornamental market. The two pages after that table list which of these chemicals (again, by active ingredient) you could use to control grassy weeds and sedges. Notice that these are divided into pre-emergence controls and post-emergence controls. Following that is our guide to herbicides that control broadleaf weeds. This, too, is divided into pre-emergence and postemergence herbicides. Note that active ingredients are listed alphabetically, starting with pre-emergents. Finally, the "Sources of Herbicides" table will provide you with a list of chemical brand names and who supplies them. On the last page, you'll find contact information for those companies. As always, use these tables for preliminary planning only. Always read and follow label instructions for each chemical you use. The Chemical Guide is not a substitute for label information. 2014 | Total Landscape Care | Chemical Guide 19
